Fish comparison
Chili Rasbora vs Neon Tetra
How the Chili Rasbora and Neon Tetra compare on care, size, water and temperament, and which fish suits your tank.
By Mike ElmiraUpdated
TL;DR, Chili Rasbora vs Neon Tetra
The Chili Rasbora and the Neon Tetra come up together a lot when people are choosing a fish, and they are close enough to weigh side by side. Both are happy somewhere around 24 to 26 °C and pH 5.5 to 6.5, so a single tank can suit either one. The Neon Tetra is the more forgiving of the two, which matters if this is an early tank, while the Chili Rasbora rewards a bit more attention. If tank space is tight, the Chili Rasbora needs less room to feel settled; give the Neon Tetra the nod when you have the litres to spare.

What to plan for
- Chili Rasbora schools, stock at least 10You've planned for 1 chili rasbora. Chili Rasbora need a group of at least 10 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
- Neon Tetra schools, stock at least 10You've planned for 1 neon tetra. Neon Tetra need a group of at least 10 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
- No bottom teamNo bottom-dwelling fish or shrimp. A small group of corydoras or a shrimp colony picks up leftover food and keeps detritus in check.
- 67% of your fish swim in the midHeavy concentration in a single zone. Spreading stocking across all three levels makes the tank read fuller for the same bioload.
